build: replace cdk version placeholder for build artifacts (#5330)

* Currently the `0.0.0-PLACEHOLDER` is still inside of the `package.json` of the material2-builds. Similar as for every other Angular package the version placeholder should be replaced with the version of the current "build commit".

Closes #5320
